Coolant loss may indicate a poorly maintained cooling system, a system fault, or even a change in driving patterns. For example, a coolant leak could have any of these causes: Overfilling the cooling system. A faulty radiator cap. A worn-out radiator hose. A leak that only occurs under certain operating conditions.

Why is my car leaking coolant?
Coolant may leak from a car for a number of reasons. The most common are: radiator corrosion; a damaged coolant hose; or a water pump with a leaky gasket. …Any coolant leak suggests your car has a serious problem – since your engine depends on coolant for its cooling system to work.
How do you check test the leakage in cooling system?
If you suspect an internal coolant leak, allow the radiator to cool, take off the cap, and look for signs of oil or frothy bubbles in the radiator or header tank. With the engine running, smell the coolant itself - if there is a whiff of exhaust gas , the cylinder-head gasket may be leaking.
Can a pressure test find a coolant leak?
Often, a leak will only be apparent when the engine is hot; as the temperature increases, the cooling system pressurises, the coolant finds the weakest point in the circuit and tries to escape. The best way to find this kind of leak is by using a pressure tester.
What are the four ways of leakage testing of the cooling system?
Coolant Concentration Test: There are different ways to perform this test. You can use alkaline test strips, a refractometer or a hydrometer, the last being the most common.
Where can my coolant be leaking from?
An antifreeze leak can occur through a hole in your radiator. Corrosion of your radiator tubes or damage because of stones or debris can create a leak. You may also see a leak between the tank and radiator body over time, as the sealing gasket wears out.

Does AutoZone do radiator pressure tester?
Use a cooling system test kit to perform air pressure tests on the radiator or coolant reservoir of any vehicle. AutoZone stocks the best cooling system test kits for cars and trucks in addition to a wide selection of replacement parts.
What tool can be used to locate small leaks in the cooling system?
A cooling system pressure tester is a vital piece of equipment to help you find this kind of leak. The tester hooks up to the radiator cap or coolant reservoir, and uses a hand pump or shop air to pressurize the system to its normal operating pressure.
How to find a coolant leak?
To locate a coolant leak, first look for puddles of coolant beneath your vehicle. If you see any, you probably have fluid dripping from somewhere in the system. With the car’s engine running, look under the hood to see if you notice any fluid flowing out. If you do, trace the fluid to its source.
What to do if you can't see a leak in coolant?
If you cannot see a leak but you are losing coolant, you may need to perform a coolant pressure test. A pressure tester is a hand-held tool that allows you to gauge the pressure inside your cooling system. If you have low pressure, you probably have a leak somewhere.
What happens if your head gasket fails?
If the head gasket fails, coolant, and engine oil may mix. You may also notice that coolant is leaking from the bottom of the engine and dripping onto the ground. Either way, a blown head gasket can be disastrous for your engine. 2.
What to do if your hose is cracked?
For example, if you have a cracked hose, replacing it is the most effective way to stop your leak. Some components naturally wear out over time. As such, replacing hoses, the radiator cap, or the reservoir tank may eventually become necessary on older vehicles. You certainly should keep an eye on hose clamps.
How hot does a car's engine get?
In fact, after running for just a few minutes, your vehicle’s engine temperature likely climbs to between 195- and 220-degrees Fahrenheit. Because that sort of extreme heat can damage engine components over time, your vehicle has a cooling system.
What happens if you don't have enough coolant?
Coolant is an essential fluid. That is, if you do not have the right amount of fluid, you are asking for serious trouble that may include substantial engine damage. As such, you should routinely check your car’s coolant levels.
Why does my car have a cooling system?
Because that sort of extreme heat can damage engine components over time, your vehicle has a cooling system. Your car’s cooling system works by pumping fluid through the engine, where it picks up heat. The fluid then moves to the radiator, where it cools before starting the cycle again. As such, if you have a car leaking coolant, ...
How much does it cost to fix a coolant leak?
A new clamp or hose might not cost you much, but an entire radiator replacement might cost between $300 and $1,200 for parts and labor, while head gasket repair can easily cost $2,000 or more.
How to fix a leaking antifreeze?
We do always recommend replacing the leaking part, but here are some other methods you can use: 1. Use Eggs.
How to get coolant out of car?
Allow the car to cool and disconnect the automotive battery. Drain all of the coolant from the system by pulling the plug out of the bottom of the radiator. Make sure you dispose of this coolant properly. Remove any hoses that connect the radiator to the engine and take off the thermostat.
How to stop a radiator leak?
Crack a couple of eggs and put them in the radiator reservoir. If the leak doesn’t stop, you can try a few more eggs. As the eggs cook, the fluid pressure will try to push them out through the holes. If all goes well, the egg will get clogged in the holes and stop the leak temporarily.
What is the head gasket on a car?
The car’s head gasket is responsible for keeping the engine oil and coolant separate. When the gasket first fails, you may not even know what’s happening because the leakage can be internal.
What is a failed water pump?
Failed Water Pump. The water pump is responsible for circulating the coolant through the system. Usually, the water pump is driven by a belt. This belt connects to the engine crankshaft, but this part is subject to corrosion and leaks. The water pump itself can also suffer from external damage that leads to a leak.
Why does my radiator fail?
1. Hole in Radiator. The radiator is subject to a lot of abuse, sitting at the front of the vehicle the way it does. Corrosion is one of the main reasons that a radiator fails, leaving a hole behind that can allow coolant to escape.
